Unconditional Generation of SkeGAN:
The effect of temperature \(\tau \)  for unconditional generation is similar to its effect in conditional generation in the case of VASkeGAN. As \(\tau \)  increases the randomness of the generated sketches also increases. Since we are investigating its effect on unconditional generation, there is no ground-truth to compare the randomness. Instead, a group of sketches generated with a particular \(\tau \)  must be compared with those generated with a different value of \(\tau \) . The influence of \(\tau \)  on \(\sigma _x\) , \(\sigma _y\)  and \(\hat{q}_k\)  is same for those in conditional generation of VSkeGAN. In addition to this, it influences the mixing weights of GMM by acting as its inverse multiplier as in [1]}. In Figure REF , there are 5 rows each depicting the sketches generated by SkeGAN at \(\tau \)  values of 0.2, 0.4, 0.6, 0.8 and 1.0. We find here that \(\tau \)  value of 0.4 is ideal for sketch generation based on visual appeal.
